Process and device for adapting the position of printing plates to the
deformation of the paper to be printed
摘要:
In a process and a device for adapting the position of printing plates (4) to the deformation (fan-out) of the paper web (2) to be printed through damp, ink absorption and mechanical stress on passing between several successive pairs of printing rolls (1) and also for adaptation to deformations possibly occuring in the fixing device of a printing roll (1) and resultant changes in the position of a printing plate (4), the printing plate (4) and/or the mount holding it in the stamping or bending machine (5) is moved or shifted laterally, in the circumferential direction and/or angularly by the amount required for said printing plate (4) on the printing roll (1) owing to said deformation of the paper web (2) to be printed, in order to obtain a print corresponding with a preceding printing roll (1), as considered in the direction of feed of the paper web, despite the paper deformation that has meanwhile occured. Thereafter the deformations, i.e. bends and/or stampings (7) are applied to said printing plate (4) moved from its zero position. For this purpose in particular a computer-controlled positioning device (17) is used in the bending and/or stamping machine (5) after the corresponding data on the paper web, the printing machine and the type of production have been fed into the computer.
